What is observed is all galaxies (except those within local clusters) moving away from each other, with the speed of recession proportional to the distance from any given point.<quoted text>
Excuse me for interupting your rant, but..... ranting does not change what the word 'observation' refers to.
What is observed is galaxies moving away from the milkyway as if it is central to the universe. What BB offers is a mess that satisfies a philosophy, the Copernican principle, and uses mysteries to explain 97% of itself.
Its obvious to anyone that understands this, that there is absolutely no justification based on the observable evidence that we are in a privileged position regarding the universal expansion.
The BB idea was founded on this observation, but far from being a "mess", it turns out that the BB made several specific predictions that were borne out in observation too. Such as the CMBR, the current ratios of lithium/helium/hydrogen, and many other more arcane but specific predictions that you can always look up i you are interested in learning instead of beating your anti-science drum.
And what "philosophy" is the BB supposed to satisfy? In fact the concept was not popular with scientists originally (but won through preponderance of evidence), and certainly not essential to the theory of evolution, which preceded it by decades.
